The 80/20 bronze wound D’Addario acoustic strings, which are sometimes referred to as brass wound, are made from the same metal alloy chosen by John D'Addario Sr. and John D'Angelico when they collaborated during the 1930s. 80/20 bronze strings are popular with some players for recording because of their bright and vibrant tone. 80/20 bronze acoustic guitar strings are also favored by many traditionalists due to their historical significance.

D'Addario phosphor bronze acoustic guitar strings were introduced by D'Addario in 1974. They have since become the most popular D’Addario acoustic strings. They have a warm, rich tone that is less bright than 80/20 bronze. Their tone also tends to last a bit longer than 80/20 bronze strings.

D’Addario’s innovative, Nickel Bronze strings for acoustic guitar feature a nickel-plated phosphor bronze winding over a high carbon NY steel core. This new wrap wire is engineered to bring out your instrument’s best qualities with an unequalled clarity, resonance and projection. D’Addario’s patented NYXL carbon steel core adds tuning stability and long life to these strings. “With Nickel Bronze, D’Addario has built a guitar string designed to let musicians re-discover their guitars all over again, giving them all new acoustic possibilities to explore,” is D’Addario’s way of saying you will find these uncoated strings amazing. Nickel Bronze strings are available in five gauge ranges from extra light (.010-.047) to medium (.013-.056), including a light top / medium bottom (.012-.056) set. All D’Addario’s strings are sealed in corrosion resistant packaging for extra long life.
D’Addario acoustic strings EXP have a very thin layer of special EXP coating bonded to their wrap wire before it is wound onto the core wire. This makes D’Addario EXP acoustic guitar strings feel more like traditional guitar strings than some other brands that coat the entire string. D’Addario says that this provides a barrier against premature wear and corrosion that can kill the life and tone of your strings. EXP strings last three or four times as long as traditional acoustic strings. D’Addario acoustic strings EXP are available in both 80/20 bronze and phosphor bronze.

D'Addario acoustic Flat Tops start as regular phosphor bronze round wound strings, and are then precision ground, which leaves the outer windings smooth and partially flat. This process creates a smooth playing string, but it does not subtract from the tone and sustain you expect from phosphor bronze acoustic strings. D’Addario Flat Tops also substantially reduce finger noise and as a result, are a good choice when you need quiet strings, such as when recording.

D’Addario Silk & Steel acoustic strings are wound with silver-plated copper wire and silk. Silk & Steel strings are much easier to finger, with a soft feel, and have a much mellower tone than traditional acoustic guitar strings. Some players prefer them on small bodied acoustic guitars and they are also popular with folk players.

D'Addario’s Gypsy Jazz strings are made to be optimal for playing in the style of Django Reinhardt. They are made from silver-plated copper wound onto a steel core, which gives them a warm tone especially suited for Gypsy Jazz guitar playing.
